Trang 1PASSIVE VOICE (CÂU BỊ ĐỘNG)
A LÝ THUYẾT
- Active voice: là cách đặt câu trong đó S giữ vai trò chủ động/ chủ
thể( essential part) hay S là người hay vật thực hiện hành động :
Eg : The workers built this house/ She bought a book
- Passive voice: là cách đặt câu trong đó S đứng vai trò bị động và O giữ
vai trò chủ động hay S nhận hành động do một chủ thể khác thực hiện
Eg: This house was built by the workers / A book was bought by her
- Bị động là hình thức nhấn mạnh vào chủ thể chịu tác động của hành động và chính hành động đó:
Bao gồm: + Chủ thể tạo tác động của hành động
+ Hành động ( Không quan tâm tới chủ thể thực hiện hành động
)
I Form:
Ex: Active: She arranges the books on the shelves every weekend.
S V O
Passive: The books are arranged on the shelves (by her) every weekend.
S be V3/ed by O
II CÁCH ĐỔI ACTIVE VOICE SANG PASSIVE VOICE:
Ex: Active sentence: Peter took this book yesterday
Passive sentence: This book was taken by Peter yesterday
Trang 2Trong câu chủ động:
- Peter → Subj ; took → động từ chính (Past simple)
- this book → Obj; yesterday → trạng từ chỉ thời gian
Trong câu bi động:
- Obj ( this book) → Subj ; Subj ( Peter) →by Obj
- thêm was vì động từ chính (took) đang chia thì Past simple
A Tổng quát:
A Tổng quát: active sentence: Subject + V + Obj
Passive sentence: Subject + BE + V3 / VED (động từ chính) + by Obj 1- Chuyển: Obj -> Subj; Subj > by Obj (Có thể bỏ nếu by Obj không
cần thiết)
2-Thêm BE và chia thì tương ứng với thì câu chủ động
Nghĩa là: Động từ chính của câu chủ động ở thì nào thì “ To Be” phải chia ở
chính có chức năng như một tính từ mang nghĩa bị động (không chia thì)3- Chuyển động từ chính sang -> V3 hoặc Vo ED
Một số công thức bị động cụ thể của các thì:
1 Present simple tense: S + is/ am/ are+ PII + by O
Eg: I drink coffee everyday -> coffee is drunk everyday
2 Present continuous tense: S + is/ am/ are+ being+ PII + by O
Trang 3Eg: Lan is listening to music at the moment -> Music is being listened to
by Lan at the moment
3 Present perfect tense: S + have/ has+ been + PII + by O
Eg: We have hired this car since yesterday -> This car has been hired sinceyesterday
4 Past simple tense: S + was/ were + PII + O
Eg: They stole a lot of money in that bank two years ago -> A lot ofmoney were stolen in that bank two years ago
5 Past continuous tense: S + was/ were + being+ PII + O
Eg: Ann was writing a letter yesterday morning -> A letter was written byAnn yesterday morning
6 Past perfect tense: S + had + been + PII + O
Eg: I had had dinner before I did my home work yesterday -> Dinner hadbeen had before my homework was done yesterday
7 Simple future tense: S + will/ shall+ be +PII +O
Eg: My father will paint our house white tomorrow -> Our house will bepainted white by my father tomorrow
8 Near future tense: S + is/ are/ am+ going to+ be +PII +O
Eg: Ann is going to work this tree -> This tree is going to be worked byAnn
9 Future perfect tense: S + will/ shall+ have been +PII +O
Eg: They will have sold their car by next Christmas -> Their car will havebeen sold by them next Christmas
Eg: I have to finish my homework now -> My homework has to befinished now
Trang 4Eg: I remember my mother taking me to the cinema when I was I child ->
I remember being taken to the cinema by my mother when I was a child
Eg: You should type this term paper -> This term paper should be type
Eg: Somebody should have called the president this morning -> Thepresident should have been called this morning
* Notes:
- Ta dùng V nguyên thể trong bị động : Be+PII để chỉ 1 ý định hay sự bắtbuộc hay sự không thể đc
Eg: This exercise is to be done
This matter is to be discussed soon
- Sau những V: to have, to order, to get, to cause hay 1 V chỉ về giácquan hoặc cảm tính ta dùng PII bao hàm nghĩa như bị động:
Eg: We had your photo taken
We heard the song sung
We got tired after having walked for long
B Cụ thể như sau:
1 Xác định Subj, Obj, Verb của câu chủ động (trong động từ phải xác định cho được thì và động từ chính của câu chủ động)
2 Chuyển: Obj -> Subj; Subj > by Obj (Có thể bỏ by
him/them/me/you/people/ someone : nếu không cần thiết)
- Nếu Subj của câu chủ động là danh từ chỉ vật liệu, dụng cụ -> câu bị động thay by bằng with + Obj
Ex: Moss is covering this wall -> This wall is being covered with moss.
Trang 5- Nếu Subj của câu chủ động là: nothing, no one, nobody -> câu bị động
bỏ by Obj và ở thể phủ định
Ex: No one helps me -> I am not helped.
3 Chuyển động từ chính sang -> V3 hoặc Vo ED
(Động từ chính có chức năng như một tính từ mang nghĩa bị động-không chia thì)
4 Thêm BE và chia tương ứng với thì của câu chủ động (Động từ chính của
câu chủ động ở thì nào thì To be phải chia ở thì đó )
5 Giữ lại động từ khiếm khuyết (Modal verb) trong câu bị động nếu có.
Will/ would, shall/ should, can/ could, may/might must, have to, be going to, used to,
Active: S+ will/would, shall/ should + Vo + object
→Passive: S + will/would, shall/should + be + V3 / Vo ED (+ by object).
Ex: Police will destroy these drugs → These drugs will be destroyed by
police
6 Đặt trạng từ chỉ thể cách (adj + ly) trước Past Participle (V3 / Vo ED) nếu
có
Ex: People use English widely → English is widely used
7 Giữ nguyên giới từ sau Past Participle (V3 / Vo ED) nếu có
8 Đặt trạng từ chỉ nơi chốn trước BY, trạng từ chỉ thời gian sau BY nếu có Place + by Obj + Time
Ex: Mr Pike built this school in my village last year.
→ This school was built in my village by Mr Pike last year
Trang 69 Past Participle (V3 / Vo ED) as an Adjective, do đó động từ theo sau hầu hết là To infinitive.
Ex: She makes me cry → I am made to cry

1-Causative form (thể truyền khuyến):
a/ Active voice: -S + Have + Obj(chỉ người) + Vo
